Cell Biology (PCB 3023) Fall 2012 Review for Exam 1 Chapter 1 List the key commonalties and differences between prokaryotic and eukaryotic cells. Prokaryotic – no organelles; no nucleus; bacteria and Achaea; spherical‚ rodlike/corkscrew-shaped; cell wall; Eukaryotic – has nucleus; has organelles Commonalities – contain DNA that stores genetic information What is the main component of cellular membranes? What function(s) do membranes serve in cells? Made of phospholipids; defines

The Role of Energy in the Body M1 Your body needs some kind energy to keep it functioning and working properly; Our bodies inherit the energy they need from food through metabolism. Metabolism is the chemical reactions in the cells that transfer the fuel from food into the energy needed in everyday life to complete daily activities. Energy is needed to get rid of oxygen from certain areas in our bodies and remove it from our bloodstream. Energy comes from; Fats Carbohydrates proteins Without

P4+M1 TASK 2 Functioning Of Body Systems Each system in the body plays an important role in energy production‚ which supports the body in many ways: giving off a variety of movements and interacts systems which supply energy for the activity. P4 What is energy? Energy can make changes possible. We use it for our every day lives‚ it helps to move cars over road and boats over water. Energy is also used to allow our bodies to grow‚ keep warm and help our minds think. Scientific define energy

Worksheet 7-A: Metabolism Exercises Name __ _________________________ Metabolism explains how the cells in the body use nutrients to meet its needs. Cells may start with small‚ simple compounds and use them as building blocks to form larger‚ more complex structures (anabolism). These anabolic reactions involve doing work and so require energy. Alternatively‚ cells may break down large compounds into smaller ones (catabolism). Catabolic reactions usually release energy. Determine whether the

Define metabolism: The sum of all biological chemical reactions inside a cell or organism Differences in catabolism and anabolism: Catabolism is an enzyme-regulated chemical reaction that releases energy. Complex organic compounds such as glucose‚ amino acids‚ glycerol and fatty acids are broken down into simpler ones. The energy of catabolic reactions is used to drive the anabolic reactions. Anabolism is also enzyme regulated but requires energy for taking the simpler broken down components

comes from the food that has been consumed. Metabolism refers to chemical reactions responsible for energy transfer within the body (Moffet‚ Moffet‚ & Schauf‚ 1993). Once food enters the body it must go through a series of chemical events in order to be converted to chemical energy ready to be utilised (McArdle‚ Katch & Katch‚ 2007). As reported by Plowman and Smith (2011)‚ the metabolic system has two main functions: anabolism and catabolism. Anabolism is a process in which energy is used to build
